Tujuan dari kegitan ini adalah untuk pengenalan dan pengembangan rancangan pembelajaran STEM (Science, Technology, Engineering, and Mathematics) dalam meningkatkan Kompetensi Guru Kimia SMA dan SMK di Kota Madiun. Mitra dalam kegitan ini adalah guru kimia yang tergabung dalam MGMP kimia SMA dan SMK di Kota Madiun. Kegiatan diikuti oleh 21 orang guru. Metode dalam kegitan ini adalah trasfer of knowledge melalui kegitan workshop. Hasil kegiatan pengabdian kepada masyarakat ini adalah: (1) mampu mencari solusi atas permasalahan yang dihadapi guru kimia di Kota Madiun, ditunjukkan oleh peningkatan capaian pemahaman melalui diklat sebesar 26,36% (dilihat dari tes awal dan tes akhir), dan (2) Pemahaman guru terhadap STEM sebesar 83,81%. Harapan peserta dan mitra kolaborasi (MGMP Kimia Kota Madiun), kegiatan semacam ini dapat secara berkesinambungan, terutama menyusun dan mengembangkan Desain Pembelajaran Berbasis STEM pada materi kimia di Sekolah Menengah dan implementasi pembelajarannya.Introduction to STEM (Science, Technology, Engineering, and Mathematics) and the Development of Learning Designs to Pioneering Chemistry Learning with the Credit System in Madiun CityAbstractThe purpose of this activity is to introduce and develop STEM (Science, Technology, Engineering, and Mathematics) learning designs in improving the Competence of High School and Vocational School Chemistry Teachers in Madiun City.
